Self-polarizing electron ring for eRHIC project

We present the electron storage ring for an arrangement of electron-proton and electron-ion collisions at RHIC. High degree of radiative electron polarization will be achieved at the beam energy range 5-10 GeV with characteristic time about 10 min. Required luminosity of polarized e-p collisions for studies of deep inelastic scattering is 1×1033 cm−2 s−1 in the SCM energy range 15-100 GeV.
